Patented Mar. it), 19rd.

To all eli/wm 'it may concern Be it known that I, MAX FUSS, a subject ofthe GermanEmperor, and a resident ot' lfrankfort-on-tl1e-l\/Iain,Germany, have invented certain new and useful Improvements in Systemsfor Treating Liquids with (lzone, 'oit which the :following is aspeciication,

This invention ri les to improvements in systems for treatinL3 liquidswith ozone for the purpose ot oxidation and destruction ot' germs, andthe object of the improvements y is to provide a System h v means ot.which such oxidation and destruction o't germs takes place inaparticularly ellectne way.

'As is well known, in systems ot this class heretofore in use theett'ect ot the ozone on the liquid wasnot .sutiieient for all purposes`because lgenerally not all the germs were ucstroyed. '.lhe reason forthe ineflcicnc) ot the systems appears to reside in the fact, that theliquid to be treated with ozone is generally l'irought. in contact withthe ozone. when flowing in a single jet, so that not all of itsparticles' come ini thorough Contact with the ozone.

This invention consists in providing' a ystem. in which the liquid whentreated with the ozone is so distributed as to present a large surfaceto the ozone, lor which purpose it is discharged in thin `jets or in thetorni of fine drops.

For the purpose ot exiiilaining'` the invention a system embodying thesaine has been shown in the accoi'npanying drawings rin which.

Figure 1,'is a vertioalsection of an apparatus llj'or treat-ingliquidwith ozone. Fig. i?. is a cross-seetion ot a portion o'l2 Fig. 1showing' the :'ipparatus t'or distributing the liquid iu a fine jetandi'or mixingr ozone therewith` lligrs, 2? to 5 arc respective.l);rplansA and a side vView o1 one member of the dislributincr :qiparatusshown in Fig. Q, Fig'. (l is a side elevation. partly in section, otanapparatus e1nliodving the invention and dii'- tering` sligrhtlwv fromthe form shown' in liej. l: Fig. 7` is a t'ront View ot' tht-'ozoni-/.eror appauatus 'for geneating the ozone required in the process, and Fig.S. is a side view ol a system comprising a plurality ot apparatus tormixing the ozone with liquid connected to a single source of ozone.

in the example of the system for treating a liquid with ozoneillustrated iu the drawvin ingsa the apparatus tor mixing the ozone andliquid is provided with a tubular plug l, whereby it can he connected toa suitable water supply` `for example to a faucet. oi. the water systemof a building. `Front the said plugr. the liquid passes through asuitahle mixing apparatus, in which it is (li-- vided into tine streams..l'nto the said mix- 111gapparatus `the ozone is drawn through apertures2 by the suction liquid. As appears more clearlyr tron1'.`l `igr. 2, themixing' apparatus consists ot :L tuhe 3 having;- a. transverse openingadapted to act as an injector or an ejector. 'lhe tulle hasscrewthreaded engagementl with a tuhular plug' 5 through which theliquid is admitted to the mixing' apparatus. The liquid passes and drawsin the ozone 2, and it flows with the same into the coni? cal part 7 ofthe Abore otl the sind 3. the walls of which flare outwardly beyond theopening 2, so that the ozone is drawn in h v the liquid7 a partialvacuum being,r created within the suction duet 2.

ll'ithin the upper part ot the ehamlier 7, the torni illustrated in Fig.l, a plurality of superimposed perforated cup shaped disks 8 arelocated. The disks are provided with perforations the disks areassembled in the chamber 7, are ott-set from each other, and the disksare held in place by teeth 10 provided on upwardly projectingr flangesot' said disks througzl'i the opening and engaging in notches S) ot theadjaeentfd1sks.

The plates are secured in place 'by means of a cap nut 11.

As the liquid passes through the 9 in the disk 8, Ait 1s divided intoity ot.l jets and is several times opening a pl uraldeflected troul ilscourse, so that. it passes through the chamber filled with ozone in astate of line distrilmtion, whereby it is thoroughlv Inixcd with theozone,

In order to keep the liquid ai; possible incontaet` with the ozone` sothat the ozone is entirely absorlibed by the liquid` the liquid is notdirectly discharged into the atniosphere, after beingmiked with theozone in the chamber 7 in the n'ianner described. .but into arcceiiitacle 1Q located aho've the mixing apparatus. The .saidrcceptaele is; so const'aioted. that the je( of liquid, by beingthmwnagainst the wall ot the receptacle, is formed 'into a thin layer long asof the stream of through the hore (5 ol the tuhc :t

S). which, when or .into line drops `tlowingjdown the wall ofv thereceptacle and through an atmosphere of ozone Ibefore it is 'dischargedthrough the spout 13."

As shown the receptacle 12 is provided with an inner shell 12, havin Vacentral .tube 12,b wliicncommunicates Wit the nozzle member 11. By thisarrangement of parts the lliquid is caused to travel in a thin sheet orseries of thin drops t-hrough the relatively narrow space`separating theouter wall of the casing 12'and t-he inner shell 12a thereof.

The ozonizer or apparatus for generating theozone which is preferablyused in the ,improved system consistsof plates forming electrodes anddielectric plates .or disks 1nterposed between 'said electrodes. T hesaid 'apparatus is thrown into operation by means o'a switch controlledby'A the pressure of oi' the device and a depending support 51'.

,theliquidto be subjected `to the influence of the ozone. Intheembodimentof the inveni tion illustrated in Fig. 1 .such switch' 1s lo-:cated below the mixing device hereinbefore ..25

described and comprises a diaphragm 50 clamped between the main castingor body 0n said support are suitably mounted terminals 52, 53 ofanielectric circuit,` and above these is arranged a circuit closingplate 54 which is maintained in `contact with the ldiaphragm by actionof a spring 55. kWhen liquid is not passing through the supply duct 1the spring 55 acts to lift. the circuit closer54 and diaphragm 50 into'the position shown inV the`drawing, in 'which said plate is out ofcontact withxthe terminals 52, '53. The pressure of liquid passingthrough the device, however, will operate to depress the .diaphragm andcircuit ,closer to set A in operation the apparatusA for gen'-A eratingozone which will be conducted tothe mixing device through the duct 2 aspre vio'usly-described. In the preferred form of the system, however,the electrical apparatus o .'the ozonizer is entirely separatedfrom theconduit for the liquid, so that the electrical vapparatus can not beinjured by the liquid, and the 'mixing apparatus can not bel-chargedwith electricity. For this purpose, the switch' is locatedl on theozonizer or within thecasin of the same, so that the electrical part othe system is *entirel separated from the mixer. The connection betweenthe-,switch and the liquid 1s made by a tube transmitting the vacuumcreated by the liquid to the switch controlling device andserving at thesame time as a duct 'for the ozone from the ozonizer into the mixingapparatus An example of ythis part of my invention is shown in Figs. 6and 7.v The ozonizer -isinclosed Within a casing 14'. The ductfortransmitting the ozone to the mixing apparatus consists of channels15, 1G7 17 and a tube 18. Bct'weenthe chanincomes nels 16 vand 17 avalve 19 is located which is normallypressed by a spring 20 against itsscat, while it bearswlith its upper surface against a diaphragm 21.- Thevalve 1s made with ports 23 and @t and with open-' ings 25 locatedperpendicularly to the latter. On the upper surfaceof 'the diaphragm aspring arm is supported which at its free -end holds a Contact 26 abovea contact 27.

The duct 15, 16, 17, and 18 communicates with the ejector 3, 1.1' whichin the example illustrated is located at the discharge side of thefaucet 28.

' In the embodiment ofthe invention illus-A trated in Fig. G, thechamber 12 oPthe form shown in Ifig. 1 is omitted, and the mixing'A tubeopens downward, or in the direction represented in Fig. 2.

The operation of the apparatus is as follows: 'When the valve onthefaucet-28 is opened, the jetof liquid passing through the ejector 3, 11creates a partial' vacuum within'. the suction ducts 18' and 17.Therefore the atmospheric pressure on the diaphragm 21 causes the valve19 to be moved from its seat against the action of the spring 20, sothat the port 23 is brought into communication with the duct 1 6.Thereby the sections 15 and 16 of the suction duct communicate .with thesections 17 and 18,-and the contacts 26 and 27 are closed, so that theapparatus torproducing the ozone is thrown into'op-r described, in whichplain disk electrodes and interposed dielectric plates are used, thedis` charge of the electricity takes place Without interruptions and inthe form of layers. 'In' apparatus of this class ,it is diiiicult tohold lio the plates at the proper Ldistances from one another, withoutunduly choking the passage of the air to be transformed into ozone, andto decrease the fields ofthe discharge. Therefore the metallic platesand the dielectric plates are held in their proper relation by means ofsmall plates. v

By the construction of the switch and its controlling vdevices so farvdescribed and projections on the said illustrated'in Figs. 6and 7 of thedrawin s the liquid is entirely 4separated lfrom t e ozonlzer and itselectrical apparatus. As

appears from Fig. 8, the same ozonizer can be provided vfor a pluralityof mixing devices. As shovvn` in -the said figure, each ot' thefaucetslt is provided with amixing apparato-.s 85, comn'lunicating withthe same ozoiuzer 36. 'It now onev of the faucets 1s opened, the liquiddlschargcd thereby draws un ozone from the .said apparatus throughthe-duct 3T, and the apparatus is automatically thrown into action bythe aforesaid switch. In order to avoid in this case the admissionof'air to the spouts from spouts which are notl in operation, so 'thatnothin but ozono is drawn'in by the liquid, cacli spout is preferablyprovided with a back pressure valve. I

In the cxain'ile illustrated in the drawings,-tl1e trans ormer and theozonizer are' inclosed withinthe same casing. Claims:
